ok lets do a test.
I will explain why keeping terrorists out of the country is independent of whether we have terrorists who are citizens
and then you can tell us why the fact we have home grown terrorists means means we should not attempt stop terrorists from coming into our country.
now remember the spineless thing to do would be to not answer the question, change the subject, say something about a conspiracy theory or trumpism or say that is not what you meant.
The truth is you and your team perform the sick calculus that you are willing to risk murderous incidents including dirty nukes in exchange for advancing your leftist goals... but your teams leaders will never admit it. So they advance their agenda on the backs of stupid people and those who are paid to go to these rallies and create photo ops for the media to push the globalist agenda.
There is no good reason to let terrorists in. If we are concerned about humanitarianism it would be far more efficient to help the legitimate refugees in their home regions and we save a ton of carbon.
